Internationalization (i18n) library for Ruby

I18n::Config#missing_interpolation_argument_handler=

Sets the missing interpolation argument handler. It can be any
object that responds to #call. The arguments that will be passed to #call
are the same as for MissingInterpolationArgument initializer. Use +Proc.new+
if you don't care about arity.

== Example:
You can supress raising an exception and return string instead:

  I18n.config.missing_interpolation_argument_handler = Proc.new do |key|
    "#{key} is missing"
  end
